>>> from django.utils.translation.trans_real import get_language_from_request
>>> g = get_language_from_request
>>> from django.http import HttpRequest
>>> r = HttpRequest
>>> r.COOKIES = {}
These tests assumes the es, es_AR, pt and pt_BR translations exit in the Django
source tree.
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'pt-br'}
>>> g(r)
'pt-br'
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'pt'}
>>> g(r)
'pt'
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'es,de'}
>>> g(r)
'es'
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'es-ar,de'}
>>> g(r)
'es-ar'
This test assumes there won't be a Django translation to a US variation
of the Spanish language, a safe assumption. When the user sets it
as the preferred language, the main 'es' translation should be selected
instead.
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'es-us'}
>>> g(r)
'es'
This tests the following scenario: there isn't a main language (zh)
translation of Django but there is a translation to variation (zh_CN)
the user sets zh-cn as the preferred language, it should be selected by
Django without falling back nor ignoring it.
>>> r.META = {'HTTP_ACCEPT_LANGUAGE': 'zh-cn,de'}
>>> g(r)
'zh-cn'
